According to the minutes of the meeting, the committee asked the Serum Institute of India to submit the updated safety data of the Phase 2/3 clinical trials, immunogenicity data from the clinical trial in UK and India, and the outcome of the assessment of UK-MHRA for grant of EUA.

During the meeting, the SII presented their proposal for grant of EUA of COVISHIELD, along with the interim safety data from Phase 3 clinical trial and interim safety and efficacy results of Phase 2/3 and Phase 3 clinical trials carried out in UK, other countries, and India, before the committee.

In the case of Bharat Biotech, the firm presented their proposal for grant of EUA, along with the interim safety and immunogenicity data of Phase 1 and 2 clinical trials carried out in the country before the committee.

“After detailed deliberation, the committee recommended that the firm should present the safety and efficacy data from the ongoing Phase 3 clinical trial in the country for further consideration,” the minutes of the meeting showed.

America’s Pfizer was the first to apply on December 4, followed by Pune-based SII and Hyderabad-based Bharat Biotech who applied on December 6 and 7, respectively. Pfizer has, however, requested more time to make a presentation before the committee.

Emergency Use Authorisation is a mechanism to facilitate the availability and use of medical countermeasures, including vaccines, during public health emergencies. Such an approval was given to Covid-19 drugs – remdesivir and favipiravir in June and itolizumab in July.

On Tuesday, the Union Health Ministry informed that as many as eight Covid-19 vaccine candidates are under different stages of clinical trials which could be ready for authorization in near future.

They include Astrazeneca and Oxford University-developed and Serum Institute of India-manufactured Covishield, Covaxin by Bharat Biotech, ZyCoV-D by Zydus Cadila, Russian vaccine candidate Sputnik-V, NVX-CoV2373 by SII, HGCO19 by Geneva, and two unlabeled vaccines – the Recombinant Protein Antigen based vaccine by Biological E Ltd, and Inactivated rabies vector platform by Bharat Biotech.
